Log-Pearson Type 3 Distribution and Its Application in Flood Frequency Analysis. I: Distribution Characteristics
Publisher: American Society of Civil Engineers
Abstract: Since the adoption of the log-Pearson Type 3 (LP3) distribution by U.S. federal agencies, it has been widely used in hydrology, but its properties are not well understood. This paper explores the characteristics of the LP3 ...

Log-Pearson Type 3 Distribution and Its Application in Flood Frequency Analysis. II: Parameter Estimation Methods
Publisher: American Society of Civil Engineers
Abstract: A number of parameter estimation methods for the log-Pearson type 3 distribution have been explored in the hydrologic literature, including the method of moments (MOM) in both log space and real space, maximum likelihood ...
Log-Pearson Type 3 Distribution and Its Application in Flood Frequency Analysis. III: Sample Skew and Weighted Skew Estimators
Publisher: American Society of Civil Engineers
Abstract: The accuracy of flood quantile estimates is constrained by the data available at a site. To improve the accuracy of quantile estimators,
